[ICOM] SSTV using MFJ-1275 with Icom 706 MarkIIG

[Dave Haney]

Our ARC has begun a weekly SSTV Net on the club's two-meter repeater. I
wanted to get involved, too, so I took the MFJ-1275 Interface I've had
sitting on the shelf for several years and tried to get it operational.
I downloaded MMSSTV and configured it as instructed, but I cannot get it
to work with my Icom-706 MarkIIG.

Since my PC has no serial port, i purchased a DB-9 (RS-232) to USB
convertor cable. I installed the software and then updated it. The
MMSSTV app says it sees COM Port 3, but still nada.

I am wondering if the jumper configuration inside the MFJ-1275 might be
the problem. The setting in the manual doesn't work. I found some other
alternate settings on some of online forums, but all they did was
immediately shut down the 706.

Any advice, jumper settings, or any other info would be greatly appreciated.
